Absolute Boilers 750-900-1050
5 Electrical
5.1 General
The Absolute Boiler is supplied with an electronic flame ionization safety control, as standard equipment. A specially
designed microprocessor is at the heart of the system. The boiler is pre-wired as shown in the wiring diagram in 12.
All external connections can be made on the terminal strips (one low voltage 24V AC and one main power voltage 120V
AC). Each boiler must be fused protected for a single phase power source 120/1/60 @ 15A, the circuit must be earth
grounded and provided with a service switch that is within hand reach.
WARNING
Electrical shock hazard can cause personal injury or loss of life, including property damage. – All electrical wiring to
the boiler and controls must be protected from ingest of water and be properly grounded and bonded according to
CEC Part I CSA 22.1 & NEC NFPA 70.
CAUTION
Label all wires prior to servicing the controls. Wiring errors can cause improper and dangerous operations
5.2 Main power voltage
Absolute Boilers require electrical power as per chart below.
The boiler is sensitive to line/neutral and therefore has a facility to ensure that line and neutral are correctly connected.
If line and neutral are crossed. The Sola control will alert/hold boiler until polarity has been corrected.
Ensure earth ground is provided and bonded correctly. The grounding must be bonded to the back panel of the control
area.
